, Letters Patent No. 114,103, dated April 25, 1871,

IMPROVEMENT lN BUCKWHEAT-REFI NERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern v Be it known that I, DANIEL D. BREWSTER, of West Laurens,.in the county of .Otsego and State of New York, have invented a new and valuable Improvement in Buckwhcat-Refiuers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making apart of this specification and to the letters and figures of referencemarked thereon.

Figure 1 ofv the'drawing is a representation of a side elevation ofmyinveution'.

Figure 2 is .a-vertical longitudinal section. My invention relates to certain improvements, hereinafter described, in buckwheat-refiners, in which the grain is broken between corrugated plates, thence conveyed to'a reel-sieve divided into several compartcars, and G attached to a rotating vertical shaft, F, the lower end of which turns in a box, f, fixed on an adj ustable cross-piece, f, operated by a set-screw at one end, the other end being hinged to the frame A. The plates 0 O are corrugated on their contiguous faces, and O has an opening in the center for the grain to drop into, after leaving the hopper, in order to be broken between said plates.

15: isa recl-sicve,-the shaft of which is jourualed t0- the frame A and upright A.

It is divided into communicating compartments I) Z) I), of which the first is finest in texture and the third coarsest.

.E is a inctalliccurb surrounding the plates 0 G, and provided with a suitable chute or trough for convcying the broken grain from the plates to the interior of said sieve.

G G are hopper-chutes, situated below the sieve to receive the contents thereof. 7 r

The former receives what falls from compartment 1), and nearly all oi'b, which is thence conveyed directly to the proper receptacle. The latter receives the contents of compartment 1) and part .of b, and directs the same through a fanhox, H, containing a fan, H, and horizontally-vibrating screens I I, which thoroughly clean and separate the coarser particles which have dropped from the coarse compartments of the sieve.

Leaving the fan-box, it passesithrough an inclined chute, Gflhommunicating with chute G.

Motion is given to the fan by means of bevel-gearing H H from the revolving shaft 1*, on which ,there is a drum, f having belt connection with the driving power.

The same shaft gives rotary motion to the shaft F by bevel-gearingl 1*, and to the reel-sieve by means of the helt-pulleys g 1, connected by the belt 9.

K-is a vibrating shoe, hung below the hopper B, and operated by a crank-arm, K, connected with the reel-sieve shaft.

L is a pitman, conveying motion from the fan-shaft v to the vibrating screens I I.

The purpose of the adjustable cross--piece fis to raise the lower plate 0' to crush the grain into finer particles.

Having described my invention,

What I claim is 1. The construction and arrangement, as heretofore described, of the sieve B, chutes G G, in combination with the fan-box H, fan H, screens I I, and

plates 0 O, as and for the purpose set forth.

2. The combined arrangement of the shafts F F, plates G O, sieve B, bevel-gearing F F H H, fan H, chutes G G, rollers g f, belt 9, and screens I I, as and for the purpose specified.

In testimony that I claim the above I' have hereunto subscribed my name in the presence of two witnesses.

DANIEL D. BREWSTER.
